Routine Description:

    This routine provides fast return of information commonly
    needed to be displayed in user interfaces.

    NT User Interface has a requirement for quick enumeration of SAM
    accounts for display in list boxes.  (Replication has similar but
    broader requirements.)

    The netui listboxes all contain similar information.  That is:

      o  AccountControl, the bits that identify the account type,
         eg, HOME, REMOTE, SERVER, WORKSTATION, etc.

      o  Logon name (machine name for computers)

      o  Full name (not used for computers)

      o  Comment (admin comment for users)

    SAM maintains this data locally in two sorted indexed cached
    lists identified by infolevels.

      o DomainDisplayUser:       HOME and REMOTE user accounts only

      o  DomainDisplayMachine:   SERVER and WORKSTATION accounts only

    Note that trust accounts, groups, and aliases are not in either of
    these lists.

Parameters:

    DomainHandle - A handle to an open domain for DOMAIN_LIST_ACCOUNTS.

    DisplayInformation - Indicates which information is to be enumerated.

    Index - The index of the first entry to be retrieved.

    PreferedMaximumLength - A recommended upper limit to the number of
        bytes to be returned.  The returned information is allocated by
        this routine.

    TotalAvailable - Total number of bytes availabe in the specified info
        class.

    TotalReturned - Number of bytes actually returned for this call.  Zero
        indicates there are no entries with an index as large as that
        specified.

    ReturnedEntryCount - Number of entries returned by this call.  Zero
        indicates there are no entries with an index as large as that
        specified.


    SortedBuffer - Receives a pointer to a buffer containing a sorted
        list of the requested information.  This buffer is allocated
        by this routine and contains the following structure:


            DomainDisplayMachine --> An array of ReturnedEntryCount elements
                                     of type DOMAIN_DISPLAY_USER.  This is
                                     followed by the bodies of the various
                                     strings pointed to from within the
                                     DOMAIN_DISPLAY_USER structures.

            DomainDisplayMachine --> An array of ReturnedEntryCount elements
                                     of type DOMAIN_DISPLAY_MACHINE.  This is
                                     followed by the bodies of the various
                                     strings pointed to from within the
                                     DOMAIN_DISPLAY_MACHINE structures.

Return Values:

    STATUS_SUCCESS - normal, successful completion.

    STATUS_ACCESS_DENIED - The specified handle was not opened for
        the necessary access.

    STATUS_INVALID_HANDLE - The specified handle is not that of an
        opened Domain object.

    STATUS_INVALID_INFO_CLASS - The requested class of information
        is not legitimate for this service.

        the prefix, then zero is returned.


Return Values:
